Claims16
A gas compression assembly for operating a refrigeration system, the compression assembly comprising an electric motor/generator, a compressor, an expansion turbine having a turbine inlet and a turbine outlet, wherein said compressor, turbine and motor/generator are integrally connected via a gear drive, a conduit for passing at least one portion of a gas in series through said compressor to said turbine and a controlling means to regulate the pressure of at least one portion of said gas passing through said turbine, and said assembly has an operating temperature of less than about 250 K in said turbine inlet.
A refrigeration process comprising:
- a) passing a gaseous mixture through a cryogenic rectification column system to separate said mixture into at least one gaseous product;
- b) passing a portion of said gaseous product into an expansion turbine of a compression assembly comprising a turbine, a compressor and an electric motor/generator integrally connected via a gear drive, wherein said turbine has a turbine inlet and a turbine outlet;
- c) passing at least one portion of said gaseous product in series through said compressor to said turbine;
- and
- d) regulating the pressure of at least said Portion of said gaseous product using a controlling means, and said assembly has an operating temperature of less than about 250 K in said turbine inlet.
